Loss of connection - forward path attenuator 6db

I have a sold connection for a few days then for no reason I will just disconnect with the green tick light flashing on the superhub not matter how many reboots I try it will not connect until I remove the "forward path attenuator 6db" from the my cable then I it will work great for 2-3 days then I will lose connection again and the only way to get it back is to connect the "forward path attenuator 6db" to the my cable. I have been doing this for the last 6-8 weeks but now getting a little peeved off with it.

Re: Loss of connection - forward path attenuator 6db

You haven't said whether or not those stats are with the FP attenuator in or out.

The power levels are well within specs. If they are with the attenuator IN then you would still be in spec if you took it out. If they are with it OUT then putting it in you'd still be in spec but marginal. What really matters is whether the voltages vary significantly. Compare over a few days and especially when you lose the connection and have had trouble re-establishing it.

Bottom line is the specs as presented look OK. The only thing unusual about then is that you appear to have two upstreams bonded. Most areas don't have bonding yet. You have one T4 (disconnect) showing in those stats. I don't know enough about log interpretation to know if the messages are especially unusual but there are a couple of T3s showing which are time-outs and will have caused a visible problem if you were using the connection.

It could just be that you have a duff Superhub - post up your story on the VM community board and let the techs there take a look - you'll need to wait up to a week for a reply from them so don't bump your post there.http://community.virginmedia.com/
